Answer to Question 1 (4 marks)
(a) 160° is more than a right angle (90°) but less than a straight line (180°), so it is obtuse. (1 mark)
(b) 300° is more than 180° but less than a full turn, so it is a reflex angle. (1 mark)
(c) A full turn is 360°; half of it is 180° and a quarter is 90°. Answer: 90°, 180° and 360°. (1 mark)
(d) Each hour mark on a clock is 360 ÷ 12 = 30° apart. At 5 o'clock the hands are 5 marks apart: 5 × 30 = 150°. (1 mark)
Answer to Question 2 (4 marks)
(a) x = 180 − 72 = 108°. (1 mark)
(b) 130 + 95 = 225. y = 360 − 225 = 135°. (1 mark)
(c) 55 + 35 = 90. z = 180 − 90 = 90°. (1 mark)
(d) 360 ÷ 4 = 90°. (1 mark)
Answer to Question 3 (4 marks)
(a) Heptagon. (1 mark)
(b) A regular polygon has all sides equal and all angles equal. An irregular polygon does not. (1 mark)
(c) 8 × 9 = 72 cm. (1 mark)
(d) 54 ÷ 9 = 6 sides (a hexagon). (1 mark)
Answer to Question 4 (3 marks)
(a) A quarter turn clockwise from north points to east. (1 mark)
(b) From east, turn clockwise in steps of 90°: south (90°), west (180°), north (270°). It faces north again. (1 mark)
(c) South is opposite north, so it needs a half turn: 180°. (1 mark)
Answer to Question 5 (5 marks)
(a) 6 × 7 = 42 m. (1 mark)
(b) 42 × 9 = £378. (2 marks)
(c) 8 × 25 = 200 cm. (1 mark)
(d) The outside turn is 360 ÷ 8 = 45°. The inside angle is 180 − 45 = 135°. (1 mark)

How to use these Year 5 angles and polygons test answers

First, sit the test under timed conditions before you read anything here. Then mark each answer and give yourself the marks shown, including method marks. When you lose marks, read the worked solution and find the step you missed. After that, revise the angles and polygons lesson and redo the worksheet.

Also, the Year 5 angles and polygons test answers are available as a PDF, so a teacher can mark printed tests quickly. Moreover, all the pages of this chapter work together, so you can move between them at any time. For example, many pupils read the lesson on Monday, practise on Wednesday and test themselves on Friday.
